Application of hyperspectral transfer functions on Raman spectroscopy. A single breast tumor biopsy was imaged using Raman microscope. The magnitude of the Raman signal is shown using a rainbow color map (a). A new transfer function is applied to separate cell types (b) based on the adjacent histology (c). Colors reflect stroma (red), epithelium (green), and protein deposits (blue). The Raman spectral distribution is shown (e) with features and baseline points indicated.
